WINBOW SASI-I.

Application filed March 5, 1924. Serial No. 697,040.

To all whom t may concern:

Be it known that l, HELEN FERGUSON, a citizen of the United States, residing at Sandwich, in the county of De Kalb and Stat-e of Illinois, have invented certain new and useful Improvements in Window Sashes, of which the following is a specification.

This invention relates to window sash structures and its consists in the novel features hereinafter described and claimed.

An object of the invention is to provide in a sash structure a frame hingedly connected with the frame of the sash and which carries the pane of glass. The frame may be swung inwardly with relation to the sash frame whereby the exterior of the pane of glass may be cleaned at the interior of the building structure.

A further object of the invention is to provide in combination with component frames hingedly connected together, sash lift devices which serve in part as means for retaining the frame elements in closed position with relation to each other.

In the accompanying drawing:

Figure 1 is a side elevational view of the sash.

Figure 2 is an enlarged detailed sectional View of a portion thereof cut on the line 3o 2 2 of Figure l.

Figure 3 is an enlarged fragmentary side elevational view of the sash showing the combined lift and securing device applied thereto and with the parts thereof disconnected from each other.

Figure 4 is a detailed transverse sectional view of the lower portion of the sash showing the combined lift and securing device applied thereto and with the parts thereof connected with each other. Y

The sash comprises an outer frame l having an inner frame 2 hingedly connected therewith by hinges 3 in a usual manner. The frame 2 carries a pane of glass t. Se-

curing devices 5 of conventional form are carried at the free edge of the frame 2 and are adapted to engage keepers 6 mounted upon the frame 1 in a usual manner. The

securing devices 5 and the keepers 6 serve in part as means for holding the frames l and 2 in closed positions with relation to each other.

Guide plates 7 are mounted upon the lower rail of the frame 2 and each plate is provided with a horizontally disposed slot 8. I

against the guide plates 7, the heads of the studs 9 pass through the vertically disposed portions of the T-shaped slots 'll and then the said studs 9 are slipped along the slot 8 and the horizontal portion of the slot 9 whereby the heads of the studs are disposed transversely across the said slots and serve as means for connecting the hasp plates to the guide plates.

When the parts of the securing devices are so connected together, the handle portions l2 of the hasp plates 10 may be freely used as gripping members for grasping the said securing devices and using them as lifts for moving the sash vertically in the window frame. The window lifts are used on the lower sash only. llVhen it is desired to clean the exterior surface of the window pane 4, the securing devices 5 are disconnected from their keepers 6 and the studs 9 are moved so that their heads are opposite the vertically disposed portions of the slots l1 in the keeper plates l0. The said keeper plates may then be swung down to the position shown in Figure 3 of the drawing and the frame 2 may be swung inwardly with relation to the frame l and consequently access may be had to the exterior surface of the pane l for cleaning the same without necessitating the Cleaner carrying on the defining hasp plate mounted upon the outer frame operation :it the exterior of the window und having a Tshaped slot adapted to regfreine.Y ister with the slot in the said guido plate, Having described the invention, what 1s the stud adapted to he passed through the 5 claimed is: Tshapred .slot and sfllppghaloilg the sume 15 A Window sash comprising inner and and the hasp plete having :it itis free end a, outer frames hinged together, a combined return bend handle portion. lift and securing,` dev-ioe comprising@ `pitite In testimony7 whereof I afiix iny signa mounted upon the inner freine and havingw a. ture. 10 slot, a stud movabiy mounted in the slot, 1 HELEN FERGUSON.
